525 mk_exim_release - Build an exim release
529 mk_exim_release [options] version PKG-DIRECTORY
533 B<mk_exim_release> builds an exim release.
535 Starting in a populated git repo that has already been tagged for
536 release it builds docs, packages etc. Parameter is the version number
537 to build as - ie 4.72 4.72-RC1, 4.86.1, etc, without any prefix.
539 This scripts expects to find a tag "exim-<version>".
541 After creating the release files, they should be signed. There is another
542 helper for creating the signatures:
543 F<release-process/scripts/sign_exim_packages>.
545 Call B<mk_exim_release> about like this:
547 release-process/scripts/mk_exim_release 4.99 OUT-DIR
554 =item B<--[no]cleanup>
556 Do (or do not) cleanup the tmp directory at exit (default: do cleanup)
560 Forces debug mode. (default: no debug info)
562 =item B<--[no]delete>
564 Delete a pre-existing tmp- and package-directory at start. (default: don't delete)
566 =item B<--tmpdir> I<dir>
568 Change the name of the tmp directory (default: temporary directory)
572 Display short help and exit cleanly. (default: don't do that)
576 Control the creation of B<lzip> tarballs. (default: do not use lzip)
578 =item B<--make> I<cmd>
580 Force the use of a specific C<make> command. This may be necessary if C<make> is not
581 C<gmake> (default: C<make>)
585 Display man page and exit cleanly. (default: don't do that)
587 =item B<--tar> I<cmd>
589 Use to override the path to the C<tar> command. Need GNU tar in case
590 I<lzip> is selected. (default: C<gtar>, if not found, use C<tar>)
594 Control the creation of the website. For creation of the website, the F<../exim-website>
595 (but see the B<website-base> option) directory must exist. (default: create the website)
597 =item B<--website-base> I<dir>
599 Base directory for the web site generation (default: F<../exim-website>)
603 Force verbose mode. (default: no verbosity)
